"I did", Davidson said, when asked by Fallon whether he had got engaged.

Grande and Davidson were dating less than a month before he popped the question.

"But I did, though", Davidson replied. "It's f-king lit, Jimmy". You ever see that Derek Jeter commercial, and he's retiring and everyone just tips their hat? "It's so amusing when you're walking down the street, and dudes, they're like." he said, as he tipped his hat.

The couple have reportedly been hard at work looking to furnish the sprawling space, with the two spotted shopping at Restoration Hardware in NY earlier this week-after Grande posted on Instagram Stories that their new place had "no furniture, one speaker, and red vines".

The Dangerous Woman singer was spotted wearing a diamond ring on her engagement finger earlier this week; it was reported on Wednesday the couple had moved into a Manhattan apartment together.

Her new fiancé - an actor and comdian best known for his sketches on SNL - split with Cazzie David, the daughter of comedian Larry David, in May.
